Spark plugs for sti hatch
Hi
I've recently bought a 2008 sti hatchback. Would anyone know which spark plugs I should be using in it? It has a fully forged engine (done by scoobyclinic) running 350bhp. I've done a few searches online but they keep coming back with different answers. Not sure what ones are in it now coz I haven't had chance to look! Would standard plugs be ok or would a colder plug be needed?
I hope someone can give me a bit of advice.
Thanks in advance

Two answers and two different grades of plug. The silfr6a is a standard plug, not sure about the ilfr7h. As mine has a little more bhp than standard should the plug be different?
Cheers
Merry Christmas everyone

Thanks for the info. Anyone recommend where to get them from? I've heard there are a lot of fakes on eBay so that could be a no no..

Just ring your local Factors and ask for NGK 5245`s they are about £11 each.
Even Opie are only £54 delivered and they arent cheap.
